  • Method of saving energy in an information handling system by controlling a main converter based on the amount of power drawn by the system
    Patent number: 7334141
    Abstract: An information handling system having an energy saving power converter that comprises a main converter for supplying power to the information handling system when in active operation, and an auxiliary converter for supplying standby power to the information handling system when in a sleep or shutdown mode of operation. The main converter is designed to supply the maximum amount of power required by the information handling system, and the auxiliary converter is designed to supply only enough power to maintain the information handling system in the sleep or shutdown mode of operation. The main converter goes into a standby or shutdown condition when not supplying power to the information handling system. The auxiliary converter is designed to draw a minimum amount of energy, only enough to maintain the information handling system in the standby or shutdown mode of operation. A voltage or current sensing logic is used to determine when the main converter should be active and when it should be in standby.
